Hair styles with these fringes might be bothersome when the curls are coming out. Keeping it short will bother having the curls coming from the roots. There's a best length for fringe that is subtle, which is not too short and not too long.

having it too short looks un-organised and too long makes it in the way. so i would recommend trimming the fringe often.

But for customers who can't come often for fringe trim, I recommend longer fringe and parting side ways.
